Abstract
The purpose of this investigation was to test the age-related measurement invariance and temporal stability of the 13-item version of Antonovsky's Sense of Coherence Scale (SOC). Multigroup structural equation modeling of longitudinal data from the Canadian National Population Health Survey was used to examine the measurement invariance across 3 age groups (19 to 25 years, n = 1,257; 30 to 55 years, n = 5,326; and ≥60 years, n = 2,213) and to compare the stability of the SOC scores obtained in 1994 and 1998 in the same participants. The results support the age-related structural invariance of the scale. Differences in the latent means and stability coefficients obtained for the three age groups provide weak to moderate support for the stability of SOC scores over time in the general population of Canada.
